White Industries Singlespeed Double Standard Engagement Freewheel - 17/19 teeth - black lockring

The freewheel double sprocket from White Industries impresses with its high-quality workmanship and extreme durability. It uses sealed industrial bearings and this has 2 advantages. No ingress of mud, sand and water. The bearing can be easily exchanged and replaced.

The highlight of the White Industries Double freewheel sprocket is that you have 2 gears on one freewheel! The simple look of the single speed bike is retained and yet you are flexible and can adapt better to the riding situation. The chain is simply shifted by hand.

In 2002 Doug White decided the world needed a better freewheel.  Until then singlespeeders seemed to be content not knowing if their freewheel would last a week or a year, or fail a mile away from home or hundreds of miles. But what was certain was failure. Overnight the ENO freewheel became the standard to measure everything else against.

Starting with a driver made from heat treated 4130 steel that houses 3 heat treated S7 tool steel pawls on the Standard Engagement model, or 6 pawls on the High Engagement model, White Industries add an 8620 steel case-hardened and electroless nickel-plated outer gear turning on an Enduro ABEC 3 or 5 grade chromium steel bearing packed with a special Mobil XHP222 extra high pressure grease.  White Industries basically designed all the weak links out of the system. And because everything wears out eventually, they designed them to be rebuildable.
